Question: I inserted Ultimate Boot CD into my CDROM drive and rebooted the computer. The reboot was as usual and no text-based menu was displayed. Have I done anything wrong?

In newer BIOSes you can press F8 (maybe also another key, not completely sure) at boot time to select from which hard drive / cdrom drive you want to boot ,without altering the boot order in the BIOS menu itself (a sort of 'boot once' option).Add also some information for booting from USB (USB-HDD, ...).

Question: I have created the Ultimate Boot CD v.1.4 as per your instructions. When I run it, the selection screen appears as expected but I have no way of selecting the options. Neither my keyboard nor my mouse are operative on the screen. Can you advise me?

Change the version number.For UBCD411, an update of isolinux/syslinux can help when you have an USB keyboard that doesn't work, but this won't be relevant for UBCD5 probably.

Question: My computer does not have the option of booting from CD in the BIOS. How can I use the Ultimate Boot CD?

Add PLoP Bootmanager. I mentioned it already to include it in the next release.It has very interesting features:

Quote:

* CDROM boot without BIOS support * USB boot without BIOS support (UHCI, OHCI and EHCI) * Floppy boot * Different profiles for operating systems * Define up to 16 partitions * No extra partition for the boot manager * Hidden boot, maybe you have a rescue system installed and the user should not see that there is another system installed * Boot countdown * Hide partitions * Password protection for the computer and the boot manager setup * Backup of partition table data * Textmode user interface 80x50 * Graphic user interface 640x480, 800x600, 1024x786, 1280x1024 * Start of the boot manager from harddisk, floppy, USB, CDROM and network * MBR partition table edit * The boot manager is freeware

Question: My computer does not have the option of booting from USB in the BIOS. How can I use the Ultimate Boot CD?

Use PLoP.

Question: I have a new Opteron system and it seems to have problems with your Ultimate Boot CD. I can boot the Windows XP setup CD, and the UBCD CD I made boots in a Pentium box, but it won't boot in my new Opteron box. Is there any way to debug what is going wrong?

Some PCs have a very buggy BIOS, which won't work correctly with isolinux. some BIOSes have only buggy USB support so that booting UBCD with syslinux from an USB thumb drive won't work, while UBCD from a CDROM works.Isolinux and syslinux have a lot of workarounds for buggy BIOSes (look at the source code ==> /core/isolinux.asm), so most PCs are able to boot isolinux based CDROMs now.

Question: Would it be possible to create a password or login script before the main menu appears? This would add a bit of security to the Ultimate Boot CD.

I think the info for cdshell doesn't matter at this moment.For isolinux you can use the following in the config files (must be used in a config file that is loaded by menu.c32 or vesamenu.c32).

Quote:

MENU PASSWD passwd

(Only valid after a LABEL statement.)

Sets a password on this menu entry. "passwd" can be either a cleartext password, a SHA-1 encrypted password (starting with $4$), or and MD5 encrypted password (starting with $1$).

Use the included Perl scripts "sha1pass" or "md5pass" to encrypt passwords. MD5 passwords are compatible with most Unix password file utilities; SHA-1 passwords are probably unique to SYSLINUX. Obviously, if you don't encrypt your passwords they will not be very secure at all.

If you are using passwords, you want to make sure you also use the settings "NOESCAPE 1", "PROMPT 0", and either set "ALLOWOPTIONS 0" or use a master password (see below.)

If passwd is an empty string, this menu entry can only be unlocked with the master password.

MENU MASTER PASSWD passwd

Sets a master password. This password can be used to boot any menu entry, and is required for the [Tab] and [Esc] keys to work.

Question: How do I edit files with the .igz extension? How do I create my own .igz files?

Add a way to do this in windows. You can use 7zip to make and unpack the .img.gz files.

These are items that I hope some kind folks can contribute to: * Tutorials for how to perform system rescue/recovery using any of the tools/utilities on the UBCD. * Update Mersenne Prime Test boot disk to allow user to manually override the decision (based on automatic CPU detection) to run V23/V24. * Update StressCPU to V2.0.

Add the link to syslinux (see answer to Magimog) to this post for the perl script.

Add also a question about how to edit the menu. Add a link to http://syslinux.zytor.com/ so that everyone can find how to edit the menus.

Add this link also at the Usefull link page.

Question: How do I edit files with the .igz extension? How do I create my own .igz files?

The IGZ files are image (img) files compressed using GZip, so you can use any tool that supports GZip compression/decompression, such as the popular 7-Zip. The igz extension is simply an abbreviation of img.gz. This is necessary because syslinux/isolinux only supports 8.3 filenames, so it will be impractical to use the full img.gz extension without abbreviation

I think that syslinux has long filename support from version 3.70 (don't know if this is the case for isolinux).

There are others around also, but I never used them, so I don't know if they are good or not.

[Contributed by IceCube] Try using PLoP Bootmanager, which supports USB boot without BIOS support (UHCI, OHCI and EHCI).

Change the second part ot the question to: Can I boot Ultimate Boot CD from a USB stick?Answer: Not directly. You can make a floppy disk or bootable CDROM which contains the PLoP Bootmanager. After PLoP Bootmanager is booted from a floppy disk or a CDROM, it is able to boot the USB stick for you when your BIOS doesn't support booting from USB (no UHCI, no OHCI and no EHCI support).

Add a question about how to unpack an remaster the iso.Use 7zip (freeware), WinRAR (shareware), ... to unpack the iso.You can also use "Daemon Tools" (freeware) to mount the iso and copy the files to a directory.

@as702 do you know about more utilities (freeware if possible)which can do that?

Isolinux still only supports 8.3 filenames.

I was already afraid for this. It realy sucks.

Good job, Victor. Maybe I will contribute to some customisation pages the folowing months, if I have time.

I know of many utilities, Icecube (it's merely a question of prioritising tasks atm). For instance, I really need to write up an instruction manaul for NwDsk to allow users to refer to customisation options available etc. A section on emulators is definitely a good idea (maybe include a list of commercial emulators alongside the freely available distributions).

If Victor would be willing, I can help update the website to help speed things up (I have some spare time approaching).

_________________"If you think things can't get any worse it's probably because you lack sufficient imagination."

UDPcast is a file transfer tool that can send data simultaneously to many destinations on a LAN. This can for instance be used to install entire classrooms of PC's at once. The advantage of UDPcast over using other methods (nfs, ftp, whatever) is that UDPcast uses Ethernet's multicast abilities: it won't take longer to install 15 machines than it would to install just 2.

- Add the link to syslinux (see answer to Magimog) to this post for the perl script.

- Add also a question about how to edit the menu. Add a link to http://syslinux.zytor.com/ so that everyone can find how to edit the menus.

- Spotted an error on the usefull link page

- StressCPU v2.0 is also freeware. I think that it is meant as GLP, because the source code is included, but it doesn't list GLP anywhere in the source code or readme file.

- CPUinfo is GLP. It is very simple script that I wrote.

- Change the second part ot the question to: Can I boot Ultimate Boot CD from a USB stick?

Done!

I didn't add it, because I think it belongs better in the FAQ page.

- Can you make subtitles in the usefull links page? Now it looks like a mess.- Add also a section in the usefull links about emulators to test a custom UBCD iso.

Will do it as soon as I have time.

I think this info best belongs on the customization page (and it is already there).

Quote:

It would be nice if you can add a short description after each program, to tell what it does (maybe a little bit longer than in the isolinux config files).

Tried it, but it makes the list looks too crowded or cluttered due to the limited space available.

Quote:

Add also photorec to the list (same author as testdisk)

I only added this one to the list (as well as to the menu). Don't want to clutter the list too much by adding too many Parted Magic related entries, just those that I would have aded to UBCD myself if Parted Magic is not present. But I have added a link to the Parted Magic entry that points to the included app list.

Quote:

Parted Magic 3.1 RC is out.

Tried RC1 under both VMWare and VPC without success. VMWare boots to the command prompt, and typing "menu" has no effect. VPC boots with an error about problems with libpciaccess.so. Have you tried it yourself?

Question: Do you have a step-by-step guide on how I can create the Ultimate Boot CD?

[Contributed by Gert Hulsemans] Here are the steps to create a CD:

1. Open your web browser. 2. Go to the Ultimate Boot CD homepage: [bhttp://www.ultimatebootcd.com/[/b]. 3. From the "Table of Content" at the left, choose "Download UBCD". 4. If you're using Windows, download "Self-extracting EXE". And after it's finished, run it. 5. If you use Linux and if you have 7z installed, you can unpack the self-extracting exe with the following command:7za e <name_of_exe_file> else download "Plain old ZIP" and extract the .zip archive. 6. You'll now have a .ISO file. Burn the .ISO file as a CD image. If you don't know how, see the question "How do I create the Ultimate Boot CD from the ISO image file?" at http://www.ultimatebootcd.com/faq.html. 7. If this still didn't work for you, maybe you should try and buy a physical CD already made for you. Select "Getting a Physical Copy" from the "Table of Content" on the website.

Separate the torrent download on the download page from the other mirror. Now it is difficult to find.
Add that the "Self-extracting EXE" is an self-extracting 7zip archive.
